摘　　要：本文采用蒙特卡洛方法,针对透射式烧蚀激光推力器真空羽流流场进行分析研究。基于烧蚀工作原理,构建了透射式激光推力器喷射理论模型,对其真空羽流流场进行了数值模拟,获得了羽流场变化过程及流场分布情况。将模拟结果与实验结果进行了比较,结果表明模拟结果与实验结果符合性良好。本文为搭载激光推力器卫星羽流场以及敏感表明污染分析提供理论基础。In this paper,Monte Carlo method is used to analyze the flow field of the vacuum plume of the ablative laser thruster.Based on the principle of ablation,a theoretical model of laser thruster injection was established,and the flow field of the vacuum plume was numerically simulated.The simulation results are compared with the experimental results,and the results show that the simulation results are in good agreement with the experimental results.This paper provides a theoretical basis for plume flow field and sensitive indication pollution analysis of satellites equipped with laser thruster.
